Just finished presenting my session for Office 365 Saturday here in Redmond. My session topic was Office 365 Hybrid Deployment with Exchange 2010 SP2. Overall the session went good, had some good questions and discussion with the audience. The only negative is that I only had 5 attendees in the room. I attribute the low number not as much to me or my topic specifically, but rather that much of the content and attendees are SharePoint focused. I am still very glad I came to present and feel it has been very worthwhile as I have met many new people and had great ad hoc discussions around infrastructure related Office 365 topics.
